Prasansuttiporn T, et al. – This research scrutinized the impact of a reducing agent and plant–extract antioxidant on the bonding durability of a self–etch adhesive to normal and NaOCl–treated, smear–layer–deproteinized dentin. Findings revealed that application of Accel (p–toluenesulfinic acid sodium salt solution) and rosmarinic acid improved bonding durability of the self–etch adhesive to both normal and smear–layer–deproteinized dentin.
